Depron 50" Slope Soarer

by apnewton | October 18, 2013 | (0) Posted in Projects

I'm just beginning in RC flight but we have had a record breaking few months of high winds, so I thought I might make something that will make use of the wind.

Here's a video of my 50" depron slope soarer. Also my first successful slope soaring session.

I used Ed's Armin wing 50" x 5" plus 1.5" flaperons and 2" elevator. Flight weight is 390g (13.8oz) with a 500mAh 2C LiPo.

and here's another session with a #16 camera onboard. Too much wind really, it was gusting to 25kn (28mph)

I have the soaring bug and want Le Fish.

Nice catch on that last vid! I've always wanted to try slope soaring, but don't live near a conducive location for it. Some day ;-)

Cheers,

Ha thanks. As you can see from the catch the fuselage had broken away from the CF boom and was rotating. Just held together with tape after numerous learner landings.

ive built three exairlines photon style slope gliders and you should give it a try too. ive used 60" wings w the 5 inch root cord and another with the 7". The 5" wing works well and the 7" flies well too but its heavier weight is better for high wind. If you reduce the fuselage tube from the standard 2" to more like 1.5 or taper it, you can reduce weight and make some pretty nice gliders that can take some punishment. ive posted one article on the site about my first slope photon and have other footage on my youtube channel. good to see others taking interest in sloping on tjis site. :) looks like you have a great location for it.

I have previously watched your Photon glider vid and loved it. My next glider might have a 60" Armin wing with Le Fish style body, we shall see.

that would be really cool to see. the LeFish design looks like a lot of fun. ive since built another 60" Armin wing with a focus on cutting down the weight to enhance glider performance. Going to a 40" 2mm dia carbon fiber spar with overlapping 10" x 2mm flat spar sections at the ends of the wings instead of a big arrow shaft, and reducing the foam spars to only a total 3x 3/4" x 30" per wing section greatly reduced the weight by almost 50% without any loss of wing performance. it also gave the wing a slightly lower profile which seems to slip thought the air faster. i might post something about it but tough to find the time. looking forward to seeing what you come up with.

In the mean time I made a Synapse (ExAir) style glider wing. Maidened it today in poor conditions and it worked well. I'll do an article as soon as I've edited up the video.

Nice work!

We've got the crazy wind up here on the NSW Central Coast as well. Most people I know are giving up trying to fly their small power models and are building wings and other slope soarers. I think my next project will probably be a slope version of the Versa Wing.
Sadly I think one of our local soaring sights at Catherine Hill Bay may just have been taken out by a bushfire though :(

I don't want to make light of bush fires, but think of the thermals! Who needs a slope?

Yes I'm looking at soaring wings too. But the 1000x350 depron sheets are not wide enough, might have to order a box of the wider sheets.
